Solution Overview
Problem
Current wireless power systems require a separate receive unit to be coupled with the device for wireless power transfer, leading to compatibility issues between different vendors' products due to the lack of standardized control channel protocols, and there is a need for cost-effective and feature-rich solutions.
Innovation Solution
The integration of a wireless power transmit unit with a processing module, transceiver, and power conversion circuit that communicates with devices using standardized or proprietary protocols, including RFID tags for communication, to facilitate efficient wireless power transfer and power management, allowing devices to be wirelessly powered without a separate receive unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate receive unit is used for wireless power transfer, then power transfer functionality is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the wireless power receive unit with the device itself, integrating the receive coil and control circuitry directly into the device structure. This eliminates the need for a separate external receive unit while maintaining wireless power transfer functionality, thereby reducing system complexity and cost.
Solution Approach 2:
The device is designed to perform multiple functions including wireless power reception, data processing, and user interaction through a single integrated unit. The receive unit within the device can communicate with multiple different transmit units from various vendors, making the device universally compatible and eliminating the need for vendor-specific external receive units.
2Adaptability or versatility
If different control channel protocols are used by different vendors, then product differentiation is achieved, but compatibility between vendor products deteriorates
Solution Approach 1:
The device incorporates a universal control channel interface that can communicate with multiple different transmit units using different protocols. The device includes protocol detection and adaptation capabilities, allowing it to automatically adjust to the protocol being used by the connected transmit unit, ensuring compatibility across different vendors while maintaining the ability to support protocol-specific features.
Solution Approach 2:
The device dynamically changes its communication parameters including protocol type, data rate, and modulation scheme based on the detected transmit unit characteristics. This allows the device to adapt to different vendor protocols while maintaining reliable communication, resolving the compatibility issue without sacrificing adaptability to specific protocol features.
3Reliability
If separate receive units are required for different devices, then power transfer is achieved, but ease of operation deteriorates
Solution Approach 1:
The wireless power receive functionality is merged into the device itself, so users only need to bring one device rather than carrying separate receive units. The integrated design allows users to simply place the device near any compatible transmit unit to receive power, eliminating the complexity of connecting external receive units and significantly improving ease of operation.

Data Source
AI summary
A wireless power system can include wireless power receive circuitry for generating power from a wireless signal, and a wireless power transceiver for communicating with a wireless power transmission unit. The wireless power system can transition from an idle state to different power management states depending on whether or not communication has been established with the wireless power transmission unit. Different modules can be activated, different supply voltages, and different clock signal rates can be used in different power management states.
